(3DShoes.com) The Marines’ Mountain Warfare Training Center located in California trains Marines in mountain and cold weather operations. During the winter, snow can reach six to eight feet high and temperatures of 20 degrees below zero. Upgrades to equipment under extreme conditions in such weather are necessary, and recent missions were able to repair equipment by using 3D printing to replace important parts of snowshoes.
Marines’ dedicated AM team 3D-printed some customized parts for snowshoes, to improve stability in the tough snowy conditions. With a 3D printed snowshoe clip, a Marine can quickly replace a clip if it breaks while they are running forward. The Additive Manufacturing team at the command worked to develop the 3D printed clip replacement for the snowshoes. It only took three days to complete them, from design phase to delivery.

André-Jacques Garnerin, (born Jan. 31, 1769, Paris, France—died Aug. 18, 1823, Paris), French aeronaut, the first person to use a parachute regularly and successfully. He perfected the parachute and made jumps from greater altitudes than had been possible before.

Amazingly, NASA is planning on sending a special helicopter to Mars, as part of their Mars 2020 rover mission.
The helicopter’s twin blades will whirl at about 10 times the rate of a helicopter’s blades on Earth — at 3,000 rpm — to stay aloft in Mars’ thin atmosphere.
“The altitude record for a helicopter flying here on Earth is about 40,000 feet [12,000 meters],” MiMi Aung, Mars Helicopter project manager at JPL, said in the statement. “The atmosphere of Mars is only one percent that of Earth, so when our helicopter is on the Martian surface, it’s already at the Earth equivalent of 100,000 feet [30,000 m] up.
“To make it fly at that low atmospheric density, we had to scrutinize everything, make it as light as possible while being as strong and as powerful as it can possibly be,” she added.

Reality may be made up of multiple universes, but each one may not be so different to our own, according to Stephen Hawking’s final theory of the cosmos.
The work, completed only weeks before the physicist’s death in March, paints a simpler picture of the past 13.8 billion years than many previous theories have proposed.

MURRIETA, CA – As a reminder to secure your property, the Murrieta Police Department posted to social media a surveillance video from this morning at a residence near Bahama and Anguilla ways in the Winchester/Winchester Creek area.
"Luckily, his doors were locked and he was not a victim," the department said. "Do the 9 pm routine. #nothinggoodhappensaftermidnight this was this morning at 4:30 am. We see you. ... so does does the entire community."

It has been about two years since Yuri Milner announced his most audacious piece of science-focused philanthropy: Breakthrough Starshot, an attempt to send hardware to Alpha Centauri by mid-century. Although the technology involved is a reasonable extrapolation of things we already know how to make, being able to create materials and technology that create that extrapolation is a serious challenge. So much of Breakthrough Starshot’s early funding has gone to figuring out what improvements on current technology are needed.
Perhaps the least well-understood developments we need come in the form of the light sail that will be needed to accelerate the starshots to 20 percent of the speed of light. We’ve only put two examples of light-driven sails into space, and they aren’t anything close to what is necessary for Breakthrough Starshot. So, in this week’s edition of Nature Materials, a team of Caltech scientists looks at what we’d need to do to go from those examples to something capable of interstellar travel.

Eila Campbell’s bucket list just got one entry shorter.
Campbell, a 94-year-old woman from Williamsport, Penn., celebrated her recent birthday by jumping out of a plane alongside her granddaughter and great-granddaughter.
“This year, when I’m going to be this age, this old, I figured I’ll never make it for another year,” Campbell told WNEP. “I better do it now.”

One day inside probably won’t hugely affect your health—but it’s not great to constantly stay cooped up from morning until dark. The biggest issue is that entering hibernation mode means you don’t get any exposure to natural light. Sunlight tends to improve your mood, and it helps your body produce vitamin D, which has been shown to help regulate the immune system, reduce inflammation in the body, and more. Sunlight also helps keep your internal body clock on schedule; your circadian rhythm plays a major part in regulating your appetite, sleep schedule, and energy levels. Research has shown that excessive exposure to electric lighting can throw off those internal rhythms.

Franz Eilhard Schulze had a laboratory full of beautiful sea creatures. In the 1880s, he was one of the world’s top experts on ocean sponges. He found many new species and filled saltwater aquariums at the University of Graz in Austria with these simple sea animals. They were striking — brightly colored with exotic shapes. Some looked like flower vases. Others resembled miniature castles with pointy towers.
But today, Schulze is best remembered for something very different — a drab little animal no larger than a sesame seed.
He discovered it one day by pure accident. It was hiding in one of his fish tanks. Creeping along the inside of the glass, it was dining on the green algae that grew there. Schulze named it Trichoplax adhaerens (TRY-koh-plaks Ad-HEER-ens). That’s Latin for “hairy sticky plate” — which is about what it looks like.
